Hey Benny,
If I'm looking at the same thing your talkin about( the de-icers), it looks like the YF-117A had them.
Unless they used the same style drawing for their color layout. But as I look too, on pg 72 of the walk around(above shot), it appears to have a "step like" object in front of the intake.
Ah never mind my friend, after awhile the different angles look the same to me!!
To remove it, try using the dremal tool w/ a small round sanding head and cut away/sand off the step.
Once that has been accomplished, go back and put a piece of Evergreen sheet styrene in the back postion of the hole.
From there fill in the remainder front section with filler/putty then once completely dry sand it to make it flush with the surface.
This sounds like a lot of work but guess what it is.. LOL
Na this should solve your problem.
As for the interior pix, I know I have seen them somewhere. I know I have pix of the production 117 interior...uuuummmmm.
More hunting I guess
Hope this helps out my friend.
Flaps up, Mike
